vacuum leak?

[lewis74]

i just finished replacing the upper control arm on the front passenger side and put the car back together. the car was on blocks for 4 days or so due to some problems getting parts in my area.
any way once i started it up to try out my new arm a new problem arrived.the car now idles lower than usual and it sputters . i have to constantly tap the gas in order to get anywhere without stalling.the only thing i touched was the box in the upper left corner with all the vacuum lines coming out of it,that i can think of that i could have messed up.

is this a vacuum prob? did a line inside or outside the box come loose..how do i check? can i open the box? or could it be something completely different?


help please!!!

Sounds like it could very well be a vacuum problem. You can take the top off and look in there. Make sure all lines are hooked up, and check for cracked lines at fittings.

1 more thing. Did you connect the electrical connectors back to the box?

i did not have to disconnect any wires

i'll open the box and look at the lines in the morn
